MACHINEV FOR ATTACHING HOOKS AND EYES TO CARDS.

Application led July 31, 1907, Serial No. 386.485. Renewed September 14, 1908.

To all whom it may concern.'

Be it known that I, WILLiAM M. Con'rimnn, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Attaching Hooks and Eyes to Cards; and I do hereby declare the following to be a full, clear, andv exact description of the invention, such` as will enable others skilled in the art to which it pertains to make and use the same.

The invention relates to means for attaching hooks and eyes to cards, and has for its object to increase the certainty and eiiciency of operation.

The invention consists in the construction hereinafter described and particularly pointed out.

away of the delivery end of the machine, showing the thread holding and thread cutting mechanism; Fig. Q() is a partial enlarged elevation of the delivery end of the machine, the view being opposite to that of Fig. 5.

Numeral 1 denotes a rotating annular table supported upon anti-friction ball bearings Q.

3 denotes a hub fixed to the table by arms 3, and 4 denotes the capital of a hollow supporting column 5. The table is turned on the bearings 2 by a shaft G having at its foot a worm gear 7 driven by a worm 8 on the vshaft 9, said shaft having a pulley 10 provided with a belt, not shown, connecting it to driving mechanism, not shown.

11 denotes an annular stationary bench surrounding the table and xed upon supports 12. This bench supports a machine 13 for sewing hooks and eyes to cards in combination with devices for moving hook and eye holders together with cards into suitable relation to the sewing machine needles 14 (see Fig. G) and for discharging them from the machine. The bed plate 91 is raised above the bench on a support 11x.

15 denotes a chute whereby the holders are discharged upon the table after the cards with attached hooks and eyes have been separated from them by sleeves or disks to be described.

17 is a driving pulley, 1S a friction clutch, 1Sx a treadle and 17x au intermediate rod and lever, which parts being well known need no further description.

Each hook and eye holder 8()X comprises a plate S1 provided with a rack or with rack teeth 29, see Figs. 14 to 1S. The ends of teeth Q9 are cut away as at 29. To these are secured side plates 83 provided with recesses 84 to receive the shank of either hooks or eyes as desired. Opposite said recessed plate is pivotally supported a plurality of spring actuated plates S2 made by preference of sheet metal and curved at their upper ends whereby they are adapted to engage a rod 85v extended through and having bearings in projections Se.

S7 denote coiled springs one end of each of which bears on the rear side of a pivoted plate 82, its opposite end bearing on a fixed abutment, preferably the rack plate, which when fixed by screw S8 or otherwise puts the spring under tension. The ofiice of the spring is to insure continued engagement of the hooks and eyes placed in the holder.

37 denotes a holder follower and 90 a support to which it is pivoted. v

19, Figs. 1, 2, 13, denote devices for supporting the holders 8Ox while being filled with hooks and eyes by operatives arranged around the bench.

20 are holder-retaining springs.

Holders to be filled are indicated in Figs. 1 and 9 to 11 and Figs. 14 to 18.

A filled card is denoted by 24 (see Fig. 2) and 25 is a card chute leading to a receptacle 26.

27 denotes an enlargement of the approximately annular bench 11 to support the sewing machine and connected parts. An 0perator at 27 places holders previously filled with hooks and eyes upon empty cards 24 which have been placed on the bed plate 91 and against a strip or ledge 92 (see Figs. 3 and 4).

29X, Figs. 6, 15, 16, is a plate fixed, one to each holder and provided with a lip 30 extending into a groove 32 in the bed plate. This lip engages the rear edge of a card resting upon the bed plate and draws it along the plate over the needle holes 14', Fig. 3, and to the discharge end of the machine when the holders are suitably moved.

33 indicates spring wires or fingers adapted to press down the holders upon the card. The lower ends of the springs bear on the tops of the holders at either side of the rack teeth, as at 292, see Figs. 14, 16 and 17. These springs are suitably held in spring clamping blocks secured by screws 34. They operate to insure the engagement of the holder racks 29 with holder-driving p inions 35 when said holders are entered by an operative under ledges 36 and then moved by the follower under springs 33. The holders are in the present instance introduced in pairs and their ends are after suitable manipulation of (zo-acting parts situated each under ledges 36 of a holder-feeder or follower 37, which is pivoted to a followercarrier or support 90. The ledges keep the holder upon the card and insure the engagement with it of lip 30. In the absence of separate means-for pressing the holder down upon the card the pressure of the holderdriving-pinions on its front end would cause its rear end to rise and thereby disengage lip 30 from the card. The proper operation of this lip or some equivalent is necessary to accurate work, and for the best results the card-moving lip extends into the groove 32. Neither the particular form nor dimensions of the lip is essential to the movement of the card by means of the holder. The follower with devices to operate it is an important means of insuring simultaneous engagement of the holder-racks with the pinions. To further insure uniformity of movement of the follower and to prevent its striking the springs 33 it is stopped by a post 34. The holder is drawn under a holder-driving gear 35 by a cord 38 running over pulleys 39 to a weight 40. This cord attached to the follower-carrier at 41.

The holders are positively moved through the machine by the pinions 35 engaging racks 29, being guided by sleeved disks 42 fixed on shafts 43 comprising flexibly connected sections 49X that carry the holder-driving pinions 35. Said shafts are supported in bearings above the bedV plate and Aare driven mediately by a ratchet wheel 44, actuated by a driving pawl 45 loosely held by an arm 46 of a lever or bar 46 journaled on a stud 46x by means of a sleeve 47. Said bar has an arm loosely connected to the arm of an eccentric strap 48 on eccentric 49 on the main driving shaft 50. in operation the eccentric rocks the lever 46 .which actuates the driving pawl 45.

45X is a circular rack loosely supported on stud or shaft 44x and actuated by a pawl 45y moved by a lever 46 until a cam or projection 62 on said rack engages a projection 61 on a pivoted lever or bar 59 with the effect to actuate a thread-cutting knife that separates or frees a filled card or the last of a group of such cards. The ratchet 44 being moved as set forth, drives, through the medium of a gear 51 fixed thereto gears 52 and 53 on the flexible shafts 43 that have each a holder moving pinion 35. The gear 51, ratchets 44 and 45X are loosely supported on a short shaft or stud 44", said gear 51 being fixed t0 the ratchet 44 and geared with pinions 52 one on each side fixed on a flexible shaft 43. As indicated in Fig. 4 the gears or pinions 52 are situated higher than pinions 35 as inferable from the showing of the shaft in Fig." 5.

52x and 53X are gears for transmitting power to remote shafts 43, suitable intermediate gears on studs being indicated by 54 and 55.

35 denotes spring pressed bearing blocks at the ends of shafts 43, which shafts comprise sections 49X connected by ball and socket joints 56. By means of these or equivalent driving shafts the axes of parallel pinions and gears may be situated in different planes. Thus the comparatively small pinions 35 are driven by means of gears of larger diameter, all being situated above a bed plate 91 of the machine, and the pinions are driven from the larger ratchet wheel all being situated above the needle plate of the sewing machine without the additional intermediate gears which would otherwise be required. It is thus also provided that the shafts may move slightly in radial direction to compensate for small variations in the dimensions of the hook and eye holders. This avoidsthe liability of disengagement between the holders and their driving pinions which might otherwise occur and particularly in case the holders or cards vary in thickness.

A furtheradvantage of shaft 4?) is that it enables a larger gear 51 and larger ratchets 44 and .45x to be used above the bed plate andfacilitates the situation of the driving pawl 45 above its ratchet wheel and in more direct connection with the main shaft 50 whereby sufficient power is attained, which cannotbe secured by the medium of the feed shaft, of the machine which has other duties -to perform.

The filled holders and cards being moved under the needles and the machine operated to: attach the hooks 57h and eyes 57e to the cards by continuous threads, these threads 57y,are cut between the last of the successive pairsof cards by la knife 57 situated adjacent and on the delivery side of certain thread-holding plungers to be described and actuated by the rod or knife handle 58 pivotally connected to a lever 59 having a fulcrum atOand provided with the tappet ,61 in thepath of the cam G2 fixed on ratchet Wheel 45". To the cutter or knife carrying arm 58 (see Figs. 5 and 7 is pivotally connectedan angular piece or trip 57 which bears on a plate 57x, fixed by a pendent bracket tobase plate 91, and against a shoulder thereon, and throws the cutter upwards when it is moved lengthwise by the arm 5S thereby cutting the threads with greater speed .and certainty, and at the saine time adding to the tension of the spring 59X whereby it retracts the cutter more quickly. ln Fig. 5 the position assumed by the rotating angular piece 57 when the movement of theknife handle has begun is indicated by broken lines. Its complete movement turns said piece down on the plate. A knife-barretnrning spring is denoted by 58x.

It ris important to successful operation that the trip 57 be triangular in forni or havefan initial or normal angular bearing such as results from the forni illustrated. The other vend of lever 59 is connected by a rod 69 toa swinging .angular piece or trip 70 adapted to engage a shoulder 71 on a bar 72 and be turned thereby. The purpose of this device is to depress bar or plate 72 and spring .supported.plungers 73 to press the threads upon the card at the last 'needle holes. This operation is sin/iultaneous with the cutting of the threads between the last card and its predecessor and serves to hold the thread while being cut. This trip or `piece 70 is made pentagonal in form substantially kas represented to insure proper engagement 0f its angles innnediately upon the shouldered plate 72 at an efficiently operative angle.

7 4 denotes screw connectionswith returning spring which movably support the bar or plate 72. Said screws take into the cross bar 77 extended laterally for the purpose. 79 are pllinger-returning springs which hold the heads 74X of' the plungers in contact with screws 75 adjustably held in bar 72, which bar, as before indicated, is loosely connected to the cross bar 77 of the fralne fixed by screws to the sewing machine base 91. The springs on screws 74 return bar 72 and springs 79 cause the plungers to follow when said bar is released from the swinging piece 70. The latter is partially rotated at. each operation being suitably connected to a pivoted swinging arm 8O and with such degree of friction that it will not overrun when partially rotated as stated.

One advantage of using a trip (70) having five or more sides is that the sides are shorter in relation to the distancefrom the center, than in a trip of rectangular form, as heretofore proposed. The result is that the trip ,is more easily operated, hence its lower side may rest flat down on the plate on which it acts.

Operatives stationed about the annular bench supplied with hook and eyes take holders from the rotating table and placing them in the holder supports 19 fill them with the hooks and eyes and then deposit them on the rotating table by which they are carried to the vicinity of the sewing machine, iwhereupon an operator places a card and holder upon the ways behind the follower-carrier and draws said carrier back over the holder thus bringing the lip 3G above the rear end of the holder, whereupon the carrier, follower, holder and card are advanced by the weight and the cord, and the loops of the hooks and eyes brought under the needles and said hooks and eyes sewed upon said card.

Each holder with its card having hooks and eyes sewed thereon is finally moved by the last gear 35 before or after the thread has been cut as specified, under a sleeve or sleeved disk 95 which presses the card with its attached hooks and eyes away from the holder and delivers the card to the opening 91x leading to chute 25 situated respectively in the bed plate 91 and below the bench 11, the holder being dropped into the chute 15 to be deposited on the rotating table and the card falling into the chute Having described the invention what I claim is,-
